A computer modeling tool for comparing novel ICD electrode orientations in children and adults. Top Row: Examples of nonstandard subcutaneous, epicardial, and transvenous electrode orientations. Left: Infraclavicular can with single subcutaneous electrode. Middle: Abdominal can with epicardial lead. Right: Infraclavicular can with superior vena cava and right ventricular transvenous electrode as well as left subcutaneous electrode.
Bottom Row: User interface for electrode placement. A subcutaneous electrode (red) extending left posterior with right abdominal can (green) is shown in a 2-year-old torso shown in 2 views used while placing electrodes in a finite element model. Moveable cutting planes allow the user to examine anatomical detail during electrode placement. The blue spheres on the red electrode and bounding cage on the can indicate handles for user interaction. Electrodes can be placed with similar precision in epicardial and transvenous orientations.
3D Segmentation were done with the EM-Segmenter in Slicer3 and bioelectric field simulation and visualization is done with SCIRun/BioPSE.

Diffusion tensor imaging tractography.: Upper left panel: Fiber tractography combined with sagittal and axial slices from a fractional anisotropy map computed with 3DSlicer. Upper right panel: Fiber tracts generated from regions of interest in the posterotemporal lobe (yellow), splenium of the corpus callosum (pink), and temporal stem (green). Lower right panel: Three- dimensional visualization of the computed trajectory of the inferior occipitofrontal fasciculus bundle (red). Read more here
